WEL Workplace Exposure Limit

Workplace Exposure Limits:
All's WEL That Ends WEL

If you work in an industry that is regulated by the Health and Safety Executive (HSE), usually the manual labour, industrial or construction sectors, then you will need to be aware of the Control of Substances Hazardous to Health standards known as COSHH.

This means that legally, employees must limit your exposure to harmful air pollutants such as paints, solvents, silica, wood dust and the fumes from cleaning chemicals by using products like face masks and respirators to protect your lungs: these are the Workplace Exposure Limits (WEL).


The amount of exposure you are subject to varies depending on how long you are in that environment, your safety equiptment and how damaging the airborne particals are.
